Justin-
Well, that's entirely your opinion. I'm sure some may agree with you, and some are going to disagree with you. They're wonderful machines, but I don't think they take the cake as the best vacuums of all time.
It seems like early Convertibles are all you talk about on here... are there other vacuums that interest you?
I would invite you to post pictures of your newly acquired models 65 and 66. Share them with us!
I would also ask, in the future, that if you're going to start a new thread -- that it please have more than one sentence making a statement. It's not conducive to creating a good conversation.
